How to do i move and settle In Singapore as a Cameroonian

You will find, on this forum, lots of good advice about how to move to Singapore, which visa types there are and what the requirements/formalities are, as well as many other aspects of life in Singapore as an expat. So I encourage you to read and follow as much of it as possible - and maybe come back with more specific questions later (which you may post here).
Do you already know what you want to do in Singapore and how you will finance it? These are usually the first questions you need to think about.
